研究概览
简要总结
The purpose of this study is to investigate to forces needed to passage the ureteroscope up and down the ureter with and without a safety guidewire in place.
详细描述
Ureteroscopy may damage the ureter, and the complication risk is influenced by the forces needed to move the ureteroscope up and down the ureter.
Although a safety guidewire (SGW) is commonly recommended in order to reduce the complication rate it may well be that the SGW itself may inhibit the passage of the ureteroscope due to increased friction.
The forces needed to move the ureteroscope in the ureter have not been investigated properly.
The intention in this study is to measure the forces needed to advance and withdraw the ureteroscope in the ureter with and without the SGW in place.

结局指标
主要结局
The force needed to passage the ureteroscope up and down in the ureter with and without SGW.
时间窗: 1 day
The force is measured by a digital force-meter device. The force measured is scaled in Newton. The results are available immediately after each measurement.
